一、引 言 测量高温的方法有许多种.一般可以区分为接触测温和非接触测温两大类.在接触测温法中通常使用热电偶,测得的是物体的真实温度,可以测到2300K左右.在更高温度的测量中,或者在某些特定的环境下,则需采用非接触的方法.大家熟知的壳度高温计是通过测量物体的亮度温度来定 I. INTRODUCTION There are many ways to measure the high temperature, which can generally be divided into two categories: contact temperature measurement and non-contact temperature measurement. In the contact temperature measurement method, a thermocouple is usually used to measure the true temperature of the object and can be measured 2300K or so. In the higher temperature measurement, or in some special circumstances, you need to use non-contact method. Well-known shell pyrometer is measured by measuring the brightness temperature of the object
